Civetone
Civetone is a macrocyclic ketone and the main odorous constituent of civet oil. It is a pheromone sourced from the African civet. It has a strong musky odor that becomes pleasant at extreme dilutions. Civetone is closely related to muscone, the principal odoriferous compound found in musk; the structure of both compounds was elucidated by Leopold Ružička. Today, civetone can be synthesized from precursor chemicals found in palm oil. Uses Civetone is a synthetic musk used as a perfume fixative and flavor. In order to attract jaguars to camera traps, field biologists have used the Calvin Klein-brand male cologne ''Obsession''. It is believed that the civetone in the cologne resembles a territorial marking.{{cite web, url=http://blogs.scientificamerican.com/thoughtful-animal/2013/10/10/youll-never-guess-how-biologists-lure-jaguars-to-camera-traps/, title=You'll Never Guess How Biologists Lure Jaguars To Camera Traps, work=Scientific American Blog Network See also * 5-Cycl ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek language, Greek () and (). Pheromones are also sometimes classified as ec ...

Musk
Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. ''Musk'' was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian ''mushk'' and Sanskrit मुष्क muṣka () derived from Proto-Indo-European noun ''múh₂s'' meaning "mouse". The deer gland was thought to resemble a scrotum. The term is applied to various plants and animals of similar smell (e.g., muskox) and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structures and molecular shapes. Natural musk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Musk
Synthetic musks are a class of synthetic aroma compounds to emulate the scent of deer musk and other animal musks (castoreum and civet). Synthetic musks have a clean, smooth and sweet scent lacking the fecal notes of animal musks. They are used as flavorings and fixatives in cosmetics, detergents, perfumes and foods, supplying the base note of many perfume formulas. Most musk fragrance used in perfumery today is synthetic. Synthetic musks in a narrower sense are chemicals modeled after the main odorants in animal musk: muscone in deer musk, and civetone in civet. Muscone and civetone are macrocyclic ketones. Other structurally distinct compounds with similar odors are also known as musks. Nitro musks An artificial musk was obtained by Albert Baur in 1888 by condensing toluene with isobutyl bromide in the presence of aluminium chloride, and nitrating the product. It was discovered accidentally as a result of Baur's attempts at producing a more effective form of trinitrotoluen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ketone
In organic chemistry, a ketone is an organic compound with the structure , where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' are methyl), with the formula . Many ketones are of great importance in biology and industry. Examples include many sugars (ketoses), many steroids, ''e.g.'', testosterone, and the solvent acetone. Nomenclature and etymology The word ''ketone'' is derived from ''Aketon'', an old German word for ''acetone''. According to the rules of IUPAC nomenclature, ketone names are derived by changing the suffix ''-ane'' of the parent alkane to ''-anone''. Typically, the position of the carbonyl group is denoted by a number, but traditional nonsystematic names are still generally used for the most important ketones, for example acetone and benzophenone. These nonsystematic names are considered retained IUPAC names, although some introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Trap
A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor—usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. Camera traps are a type of remote cameras used to capture images of wildlife with as little human interference as possible. Camera trapping is a method for recording wild animals when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, and research on habitat use and occupation of human-built structures. Since the introduction of commercial infrared-triggered cameras in the early 1990s, their use has increased. With advancements in the quality of camera equipment, this meth ...

Mammalian Pheromones
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the larger ...

Macrocycles
Macrocycles are often described as molecules and ions containing a Ring (chemistry), ring of twelve or more atoms. Classical examples include the crown ethers, calixarenes, porphyrins, and cyclodextrins. Macrocycles describe a large, mature area of chemistry. Synthesis The formation of macrocycles by ring-closure is called macrocyclization. The central challenge to macrocyclization is that ring-closing reactions do not favor the formation of large rings. Instead, medium sized rings or polymers tend to form. Early macrocyclizations were achieved ketonic decarboxylations for the preparation of terpenoid macrocycles. So, while Ružička was able to produce various macrocycles, the yields were low. This kinetic problem can be addressed by using high-dilution reactions, whereby intramolecular processes are favored relative to polymerizations. Reactions amenable to high dilution include Dieckmann condensation and related based-induced reactions of esters with remote halides. So ...

Perfume Ingredients
Perfume (, ) is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of artificial mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory." Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin and coumarin, which allowed for the composition of perfumes with sme ...

Eau De Cologne
Eau de Cologne (; German: ''Kölnisch Wasser'' ; meaning "Water from Cologne") or simply cologne is a perfume originating in Cologne, Germany. Originally mixed by Johann Maria Farina (Giovanni Maria Farina) in 1709, it has since come to be a generic term for scented formulations in typical concentration of 2–5% and also more depending upon its type of essential oils or a blend of extracts, alcohol, and water. In a base of dilute ethanol (70–90%), eau de cologne contains a mixture of citrus oils, including oils of lemon, orange, tangerine, clementine, bergamot, lime, grapefruit, blood orange, bitter orange, and neroli. It can also contain oils of lavender, rosemary, thyme, oregano, petitgrain (orange leaf), jasmine, olive, oleaster, and tobacco.
